ISO 28704:2011标准规定了多孔陶瓷材料在室温下进行循环弯曲疲劳试验的方法。该标准适用于多孔陶瓷材料，包括氧化铝、氧化锆、氧化钇、氧化铈等材料。试验的目的是评估材料的弯曲疲劳性能，以便在实际应用中确定材料的可靠性。

ISO 28704:2011标准要求在试验前对试样进行表面处理，以消除试样表面的缺陷和损伤。试样的尺寸和形状应符合标准规定，并且应该在试验前进行称重和测量。试验时，试样应该被放置在弯曲试验机上，并且应该施加一定的载荷，以产生弯曲应力。载荷的大小和频率应该符合标准规定。

在试验过程中，应该记录试样的弯曲次数和载荷大小，并且应该定期检查试样的表面状态。试验结束后，应该对试样进行称重和测量，以确定试样的疲劳损伤程度。

ISO 28704:2011标准还规定了试验结果的处理方法。试验结果应该包括试样的疲劳寿命和疲劳损伤程度。试验结果应该进行统计分析，并且应该绘制疲劳曲线和疲劳寿命分布曲线。
